Re: '67 Engine Temp Readings - What Ya Think
Your exhaust manifold temperatures are good. They indicate whether the engine has the correct total idle timing, and they should be no more than about 500 F on a non emission controlled car.
A ported vacuum advance system used on emission controlled engines will raise the exhaust manifold temperature several hundred degrees.
